Abstract

We present a study of multiphoton dissociative ionization from molecules. By solving the time-dependent Schrödinger equation for H(2)(+) and projecting the solution onto double continuum scattering states, we observe the correlated electron-nuclear ionization dynamics in detail. We show-for the first time-how multiphoton structure prevails as long as one accounts for the energies of all the fragments. Our current work provides a new avenue to analyze strong-field fragmentation that leads to a deeper understanding of the correlated molecular dynamics.
